The new portable analyzer is compact, lightweight, and battery powered for on-site HF measurement. With an on-board pump and connections for Teflon tubing, the target gas is continuously transferred into the internal measurement cell. Due to the digital low power design, the analyzer is operational for an entire shift with one battery charge.
The analyzer provides reliable operation with instantaneous response and sufficient dynamic range to measure sub ppm and several hundred ppm HF concentrations. In contrast to many other measurement techniques, short-term HF peaks are uncovered with the LaserGas III.
Other gases such as NH3, HCl, and H2S will be implemented consecutively and are available on request.
